Explanation:
Pressure = force / area
P = (68 kg × 9.8 m/s²) / (2 × (0.04 m)²)
P = 208,250 Pa
Converting to psi:
P = 208,250 N/m² × (0.225 lbf/N) × (0.0254 m/in)²
P = 30.2 psi

Explanation:
La infección por Salmonella (salmonelosis) es una enfermedad bacteriana común que afecta el tracto intestinal. ... Los humanos se infectan con mayor frecuencia a través de agua o alimentos contaminados. Por lo general, las personas con infección por salmonella no tienen síntomas. Otros desarrollan diarrea, fiebre y calambres abdominales dentro de las ocho a 72 horas.
Answer:
Since Fluorine is very electronegative, it can easily absorb the electrons of other elements. Since it sucks up electron, this gives Fluorine an excess electron thus making it a negative ion F-.
Explanation:
because it is
Answer:
2 m/s².
Explanation:
The forces acting on the crate have been shown in the figure below.
Net force acting on the crate in the horizontal direction = 400 - 250 = 150 N towards right.
For the forces of vertical direction we can write,
Normal force = 150 + Mg = 150 + 250 = 400 N (here g = 10 m/s² have been taken)
The magnitude of frictional force that will act on the crate = μ × Normal force
So, Frictional force = 0.25 × 400 = 100 N
Thus, the net force that will cause acceleration in the crate will be
Force in the right direction - frictional force
= 150 - 100 = 50 N
As we know,
Acceleration = 
= 
= 2 m/s²
So, the net acceleration in the crate will be 2 m/s².
Earthquakes does not belong because it is not an electromagnetic wave.
